    Title Phylogeographical Structure and Temporal Complexity in American Sweetgum (liquidambar Styraciflua; Altingiaceae).
    Date October 2008
    Journal Molecular Ecology
    Excerpt

    Eastern North American plant biogeography has traditionally focused on two primary issues: (i) the location of temperate Pleistocene refugia and their proximity to the southern margin of the ice sheet during the last glacial maximum, and (ii) the origin of the temperate element of northern Latin America. While numerous population genetic and phylogeographical studies have focused on the first issue, few (if any) have considered the second. We addressed these issues by surveying 117 individuals from 24 populations of Liquidambar styraciflua (American sweetgum; Altingiaceae) across the southeastern USA, eastern Mexico, and Guatemala, using more than 2200 bp of chloroplast DNA sequence data. To specifically address the issue of timing, we estimated intraspecific divergence times on the basis of multiple fossil-based calibration points, using taxa from Altingiaceae (Liquidambar and Altingia) and Hammamelidaceae (Hamamelis) as outgroups. More than half of the sampled localities exhibited multiple haplotypes. Remarkably, the greatest variation was observed within the USA, with Mexico and Guatemala sharing widespread haplotypes with Texas, Mississippi, Kentucky, Ohio, and northern Virginia. This lack of differentiation suggests shared ancestral polymorphisms, and that the genetic signal we observed is older than the disjunction itself. Our data provide support for previously proposed hypotheses of Pleistocene refugia in peninsular Florida and along the eastern Atlantic, but also for deeper divergences (approximately 8 million years ago) within the USA. These patterns reflect a dynamic biogeographical history for eastern North American trees, and emphasize the importance of the inclusion of a temporal component in any phylogeographical study.

    Title Comparative Phylogeography of Unglaciated Eastern North America.
    Date January 2007
    Journal Molecular Ecology
    Excerpt

    Regional phylogeographical studies involving co-distributed animal and plant species have been conducted for several areas, most notably for Europe and the Pacific Northwest of North America. Until recently, phylogeographical studies in unglaciated eastern North America have been largely limited to animals. As more studies emerge for diverse lineages (including plants), it seems timely to assess the phylogeography across this region: (i) comparing and contrasting the patterns seen in plants and animals; (ii) assessing the extent of pseudocongruence; and (iii) discussing the potential applications of regional phylogeography to issues in ecology, such as response to climatic change. Unglaciated eastern North America is a large, geologically and topographically complex area with the species examined having diverse distributions. Nonetheless, some recurrent patterns emerge: (i) maritime - Atlantic vs. Gulf Coast; (ii) Apalachicola River discontinuity; (iii) Tombigbee River discontinuity; (iv) the Appalachian Mountain discontinuity; (v) the Mississippi River discontinuity; and (vi) the Apalachicola River and Mississippi River discontinuities. Although initially documented in animals, most of these patterns are also apparent in plants, providing support for phylogeographical generalizations. These patterns may generally be attributable to isolation and differentiation during Pleistocene glaciation, but in some cases may be older (Pliocene). Molecular studies sometimes agree with longstanding hypotheses of glacial refugia, but also suggest additional possible refugia, such as the southern Appalachian Mountains and areas close to the Laurentide Ice Sheet. Many species exhibit distinct patterns that reflect the unique, rather than the shared, aspects of species' phylogeographical histories. Furthermore, similar modern phylogeographical patterns can result from different underlying causal factors operating at different times (i.e. pseudocongruence). One underemphasized component of pseudocongruence may result from the efforts of researchers to categorize patterns visually - similar patterns may, in fact, not fully coincide, and inferring agreement may obscure the actual patterns and lead to erroneous conclusions. Our modelling analyses indicate no clear spatial patterning and support the hypothesis that phylogeographical structure in diverse temperate taxa is complex and was not shaped by just a few barriers.

    Title Factors Associated with Drug Adherence and Blood Pressure Control in Patients with Hypertension.
    Date October 2006
    Journal Pharmacotherapy
    Excerpt

    To determine characteristics associated with drug adherence and blood pressure control among patients with hypertension, and to assess agreement between self-reported and refill adherences.

    Title Protease Inhibitor Use in 233 Pregnancies.
    Date November 2005
    Journal Journal of Acquired Immune Deficiency Syndromes (1999)
    Excerpt

    In the United States, as most highly active antiretroviral therapy (HAART) regimens used during pregnancy in HIV-infected women include a protease inhibitor (PI), it is important to determine the effects of PIs specifically rather than all HAART regimens. Prospective trials employing HAART during pregnancy are ongoing.

    Title Association Between Adherence Measurements of Metoprolol and Health Care Utilization in Older Patients with Heart Failure.
    Date March 2005
    Journal Clinical Pharmacology and Therapeutics
    Excerpt

    Data from electronic dosing monitors and published pharmacokinetic parameters were used to derive medication adherence measures for immediate-release metoprolol and examine their association with health care utilization of outpatients aged 50 years or older with heart failure.

    Title Pain Behaviors Observed During Six Common Procedures: Results from Thunder Project Ii.
    Date March 2004
    Journal Critical Care Medicine
    Excerpt

    Patients frequently display behaviors during procedures that may be pain related. Clinicians often rely on the patient's demonstration of behaviors as a cue to presence of pain. The purpose of this study was to identify specific pain-related behaviors and factors that predict the degree of behavioral responses during the following procedures: turning, central venous catheter insertion, wound drain removal, wound care, tracheal suctioning, and femoral sheath removal.

    Title Practices and Predictors of Analgesic Interventions for Adults Undergoing Painful Procedures.
    Date January 2003
    Journal American Journal of Critical Care : an Official Publication, American Association of Critical-care Nurses
    Excerpt

    Research is limited on analgesic practices associated with the commonly performed procedures of turning, inserting central venous catheters, removing wound drains, changing dressings on nonburn wounds, suctioning the trachea, and removing femoral sheaths.

    Title Translating Research into Practice. Implications of the Thunder Project Ii.
    Date July 2002
    Journal Critical Care Nursing Clinics of North America
    Excerpt

    The Thunder Project II study described procedural pain in a variety of acute and critical care settings. The procedures studied were turning, tracheal suctioning, wound drain removal, nonburn wound dressing change, femoral sheath removal, and central venous catheter insertion. Turning had the highest mean pain intensity, whereas femoral sheath removal and central venous catheter insertion had the least pain intensity in adults. Nonwound dressing change had the highest pain intensity for teenagers. Pain occurred in procedures that are often repeated several times a day as well as in those that may be single events. There is a wide range of pain responses to any of these procedures; as a result, standardized and thoughtful pain, and distress assessments are warranted. Planning of care, including the use of preemptive analgesic interventions, needs to be individualized. Future studies are needed to describe patient responses to other commonly performed nursing procedures and to identify effective interventions for reducing procedural pain and distress.

    Title Patients' Perceptions and Responses to Procedural Pain: Results from Thunder Project Ii.
    Date December 2001
    Journal American Journal of Critical Care : an Official Publication, American Association of Critical-care Nurses
    Excerpt

    Little is known about the painfulness of procedures commonly performed in acute and critical care settings.

    Title Tolerability of Enteric-coated Didanosine Capsules Compared with Didanosine Tablets in Adults with Hiv Infection.
    Date December 2001
    Journal Journal of Acquired Immune Deficiency Syndromes (1999)
    Excerpt

    A new enteric-coated (EC) didanosine (ddI) formulation (Videx EC; Bristol-Myers Squibb, Princeton, NJ, U.S.A.) may be better tolerated than the tablet form because it lacks the buffer component thought to be responsible for diarrhea and other gastrointestinal (GI) side effects.

    Title Multicenter Review of Protease Inhibitors in 89 Pregnancies.
    Date January 2001
    Journal Journal of Acquired Immune Deficiency Syndromes (1999)
    Excerpt

    CONTEXT: Despite the success of highly active antiretroviral therapy, the optimal approach for preventing perinatal HIV-1 transmission is not known. OBJECTIVE: A retrospective survey was conducted at six centers in the United States and Puerto Rico from January 1997 to October 1998 to evaluate the effects of protease inhibitor use during pregnancy on maternal and infant safety, prematurity rate, and frequency of perinatal HIV-1 transmission. RESULTS: In the study, 91 live infants, including 3 sets of twins, and 1 neonate who died shortly after birth were born to 89 women. HIV perinatal transmission rate in this series was 0 (95% confidence interval [CI], 0%-3%). Prematurity rate was 19.1%, comparable to rates in earlier reports of HIV-1-infected women. In multiple regression analysis, only cocaine use and premature rupture of membranes were associated with prematurity (p =.03 and.008, respectively). The gestational week during which the protease inhibitors were initiated was not found to be significantly associated with prematurity. Adverse maternal, obstetric, and infant events possibly related to protease inhibitors were uncommon. CONCLUSIONS: Protease inhibitors appeared generally safe in mothers and infants in this series. No perinatal HIV-1 transmission occurred. Further prospective, controlled studies are needed to define the optimal management of HIV-1 in pregnancy.

    Title Versatile, High-speed Force Transducer Using a Laser Diode Beam As an Optical Lever.
    Date March 2000
    Journal Journal of Applied Physiology (bethesda, Md. : 1985)
    Excerpt

    A force transducer with variable sensitivity and speed is described. Its moving element is a cantilever beam that projects vertically into a muscle bath. A brace constrains bending of the beam to a short, proximal "hinge." Rotation of the beam about the hinge is amplified 30-fold by an optical lever consisting of a laser diode beam reflected from a mirror on the cantilever to a photodiode pair. This design places the electrical components at a distance from the damp environment of the muscle bath. Large changes in sensitivity and speed can be obtained by substituting different cantilevers. Smaller changes can be made by varying the length of the hinge. A transducer with a 6-mm cantilever optimized for the study of single, skinned skeletal muscle fibers is described in detail. This device had a resonant frequency of 22 kHz and sensitivity such that the total root-mean-square noise in the circuit was more than 500-fold smaller than the expected maximum force. Variations of this device with orders of magnitude different sensitivities are also described.

    Title Failure to Cure Mycobacterium Gordonae Peritonitis Associated with Continuous Ambulatory Peritoneal Dialysis.
    Date July 1997
    Journal Clinical Infectious Diseases : an Official Publication of the Infectious Diseases Society of America
    Excerpt

    Nontuberculous mycobacteria are increasingly recognized as important pathogens in peritonitis associated with continuous ambulatory peritoneal dialysis (CAPD). Mycobacterium gordonae rarely causes human infection and is the least likely mycobacterium to produce clinical infection in CAPD patients. We describe a patient with persistent M. gordonae peritonitis acquired while undergoing CAPD. During 18 months of treatment, clinical improvement occurred but a microbiological cure could not be achieved. Principles of therapy for mycobacterial peritonitis developing during CAPD are reviewed, and potential explanations for our patient's failure to respond to therapy are discussed.

    Title Sinonasal Non-hodgkin's Lymphoma in Patients Infected with Human Immunodeficiency Virus: Report of Three Cases and Review.
    Date November 1995
    Journal Clinical Infectious Diseases : an Official Publication of the Infectious Diseases Society of America
    Excerpt

    Non-Hodgkin's lymphoma (NHL) is a frequent complication of human immunodeficiency virus (HIV) infection, but involvement of the sinonasal region has only rarely been reported. We report three cases of AIDS-associated sinonasal NHL that occurred at our institution and review eight cases that were reported in the literature. The epidemiological and clinicopathologic features of these cases are described and compared with those of three other groups of patients: non-HIV-infected patients with sinonasal NHL, HIV-infected patients with NHL of any anatomic site, and HIV-infected patients with infectious sinusitis. Patients with AIDS-associated sinonasal NHL more frequently developed bony erosion and presented with signs and symptoms referable to adjacent structures, such as the orbit, than did HIV-infected patients with sinusitis, and patients with AIDS and NHL less frequently had typical sinus symptoms and diffuse sinus involvement than did patients with sinusitis. However, the clinical manifestations of these conditions overlap; thus a high index of suspicion for NHL is imperative for prompt diagnosis. These lymphomas typically are high-grade and disseminate early, and the prognosis is generally poor.

    Title Use of Rifampin in Nonstaphylococcal, Nonmycobacterial Disease.
    Date March 1993
    Journal Antimicrobial Agents and Chemotherapy
    Excerpt

    Rifampin has very broad antimicrobial properties with in vitro activities against many bacteria, mycobacteria, higher bacteria, chlamydia, fungi, parasites, and viruses (Table 1). The clinical use of rifampin is more limited, in part because of the lack of in vivo human clinical studies demonstrating its efficacy. Investigators have valid concerns regarding the emergence of resistance of mycobacteria if widespread use of rifampin becomes common, although this has not been well documented. Because rifampin obtains therapeutic levels intracellularly and is distributed widely throughout the body, the antibiotic potentially could be used on a broader scale, but more studies will be needed to demonstrate its clinical utility.

    Title Gallbladder and Biliary Tract Candidiasis: Nine Cases and Review.
    Date July 1990
    Journal Reviews of Infectious Diseases
    Excerpt

    We review biliary tract and gallbladder candidiasis and define patient demographics, risk factors, prognostic factors, and treatment strategies for this infection. This is a 3-year retrospective review of our experience with this disease and a review of the English-language literature. Thirty-one cases of biliary tract and gallbladder candidiasis, including nine in our series, have been examined. The same risk factors that predispose patients to other forms of candidal infection are implicated here. No mortality was found with uncomplicated candidal cholecystitis in nonneutropenic patients treated with cholecystectomy alone. Patients with associated extrabiliary tract candidiasis or candidemia had worse outcomes and required both surgical intervention and antifungal therapy. When risk factors exist for the development of biliary tract or gallbladder candidiasis, the physician should be alert to this possibility. There is no need for antifungal therapy in cases of isolated candidiasis of the gallbladder in nonneutropenic patients.

    Title Clonal Structure of Wild Populations and Origins of Horticultural Stocks of Illicium Parviflorum (illiciaceae).
    Date
    Journal American Journal of Botany
    Excerpt

    • Premise of the study: Habitat fragmentation is often assumed to result in limited genetic diversity across impacted plant communities. Central Florida has undergone extensive anthropogenic changes, while also harboring large numbers of endemic species. In this study, we assessed genetic structure and dependence on clonality in a central Florida endemic, Illicium parviflorum (Illiciaceae), as well as evaluated genetic diversity of this species in horticultural stocks. • Methods: Six sites were sampled across the geographic range of I. parviflorum. A PCR-based assay using intersimple sequence repeats (ISSRs) was used to assess genetic structure. • Key results: Results, based on 26 ISSR loci, suggest that clonal structure plays a role in all populations, with PD values ranging from 0.25 to 0.50. Only two populations exhibited unique genotypes, while the remaining four populations shared genotypes. Horticultural samples all shared one genotype, which can be traced back to a single natural population. • Conclusions: Clonal reproduction is an important factor in the maintenance of natural populations of I. parviflorum, although the degree to which this is true varies by population. Horticultural samples likely represent a single or very few collection events, indicating the need for greater genetic diversity within horticultural stocks. Further analyses using microsatellites are planned to confirm these results.

    Title Stratified Analysis of the Soil Seed Bank in the Cedar Glade Endemic Astragalus Bibullatus: Evidence for Historical Changes in Genetic Structure.
    Date
    Journal American Journal of Botany
    Excerpt

    Persistent seed banks may provide information on historical changes in the genetic composition of populations. We used stratified sampling of the soil seed bank of Astragalus bibullatus (Pyne's ground plum) to assess levels of temporal variation in population genetic structure and to infer historical changes in the levels of inbreeding and relative gene flow. This species has an extremely limited distribution in the Central Basin of Tennessee, where it is found in open areas and along the edges of cedar glades. Protein electrophoresis was conducted on seedlings grown from seeds that had been recovered from three successive 1 cm thick layers of soil sampled from six sites. Analyses of seven polymorphic allozyme loci indicated that there were substantial levels of genetic differentiation among soil layers and sites. Higher levels of genetic diversity were found in seed than in vegetative populations that had been sampled in a previous study. Seed populations from the uppermost soil layer had higher heterozygote deficiencies, displayed higher levels of differentiation among sites, and had higher private allele frequencies than seed populations from the lower two layers. The change in heterozygosity and distribution of genetic variation among sites for the youngest soil layer is consistent with a pattern of increased selfing, sib mating, and decreased gene flow among populations. These changes in inbreeding and relative levels of gene flow are corroborated by information on historical land use practices in the region and support the hypothesis that loss of appropriate habitat has led to smaller population sizes and a more fragmented distribution of this cedar glade endemic.
